As indicated in this comment, I prefer reusing the existing GetBlockVerboseResult and populate the Tx field, since it's desirable to be compatible with Bitcoin Core.

You'll need to update the type of Tx field in the original GetBlockVerboseResult like this:

Tx            []TxRawResult `json:"tx,omitempty"`
